CWNP Certified Wireless Analysis Professional 認定 CWAP-402 試験問題:

1. You are troubleshooting a connection problem with a client STA. Regardless of the AP to which it attempts to connect, the connection fails. Using a wired protocol analyzer, you determine that the problem is with the 802.1X/EAP authentication to the RADIUS server.
What layer or range of layers of the OSI model revealed this information?

A) Layer 3
B) Above Layer 4
C) Below Layer 3
D) Layer 2

2. You have been recently hired as the wireless network administrator for an organization spread across seven locations. They have deployed more than 100 APs, but they have not been managed in either an automated or manual process for more than 18 months.
Given this length of time, what is one of the first things you should evaluate from a support perspective?

A) The VLANs in use
B) The data rates allowed
C) The channels in use
D) The firmware revision

3. A new firmware has been released for the AP model you use in your WLAN. You have more than 120 of these APs installed.
What is a good reason for applying a firmware update on an enterprise AP?

A) Disable lower data rates
B) Enable new security features and patch vulnerabilities
C) Enable the short guard interval
D) Enable 4x4:4 spatial streams on a 3x3:3 AP

4. You are explaining capacity planning to another engineer assisting you on a WLAN implementation project. As part of the explanation, you provide the following formula: C = B
* log2(1 + S/N).
What does this formula define?

A) The WEP encryption algorithm
B) Maximum signal strength of a channel
C) Minimum signal strength for a data rate
D) Bandwidth capabilities of a channel

5. You have implemented centralized, infrastructure-based spectrum analysis. The Aps are configured to perform spectrum analysis in an ad-hoc manner and will go offline as Aps to perform this duty when needed.
What unique method of spectrum analysis monitoring is provided by this solution that is not typically available in a laptop-based analyzer?

A) Band selection
B) RBW adjustments
C) Web-based viewing
D) Real-time FFT
